Climate Change and Terrorism

Last month, after the terrorist attacks in Paris, Nature published a Q & A with an anthropologist who studies the murderous motivations of Islamic extremists. He discussed socio-cultural factors and an allure to a radical ideology. That may help explain Islamic attacks against "infidels" in Europe and the United States, but then what's driving suicide bombers in Somalia, Pakistan, and Iraq where it's Muslims killing Muslims? Is there a common denominator? On Twitter, Jeff Goodell points suggestively to his current story at Rolling Stone magazine.
